COTTON-PRESS.

l SPECIFICATION forming-part of Letters PatentNo. 284,208, dated September 4, 1883. Application filed uguste, 1881. (Model) To all whom itmwy concern;

Be it known that I, EDM ND M. IvnNs, of New Orleans, in the parish of Orleans and State of Louisiana, have invented Improvei5 ments in Cotton-Presses, of whichthefollowing is a specification.

These improvements consist, first, in the e combination, with the upper platen, of mechanisni hinged to the saidplaten in such many to leave space for the introduction of the bagging, and afterward turned down to fill the space between said platen and the upper edge ner as to admit of'their being turned upward of the side doors, to prevent the latter from rising by the friction of .the cotton thereon while being pressed upward; secondly, in the formation of the socket on under side of the follower slightly conical, in combination with ing or bending of saidscrew in case of uneven filling of the cottonechamber, making one end of the bale heavier or thicker than the other; thirdly, in a novel construction of the pressure-plate on which the collar or flange of the screw-nut revolves, forming an oil-basin in a lock-chain fastening to the strain-beams on-the main doors of the compression-chamber, in combination with tenoned' washerplates on said strain -beams, for purposes hereinafter described. l

Referring to the accompanying drawings,

Figure 1 represents a front elevation of a press,

showing some of my improvements. Fig. 2 is a vertical section of the saine, with the screw in elevation. Fig. 3 is a side view of the upper portion of the cotton-box or compressiona chamber. .Fig. 4, is a face view, on an enlarged scale, of one of the washer-plates at tached to the strain-timbers at each corner.

, Fig. 5 is an edge view of the same. Fig. 6 is a section showing the lateral supply-chamber and follower. Fig. 7 is a top or face view of the pressure-plate, forming an oil-well for the screw-nut to revolve in, and admitting of its extension through the strain-beam for the attachment of the draft-beams. Fig. 8 is a central section of the same 011 the line as x 011 Fig.7.

The same letters occurring on the several figures indicate like parts.

A represents the cotton-box, and A its upa cylindrical end of the screw, to avoid springto prevent cutting and waste of oil; fourthly,

I per portion or compression-chamber, which is provided with a platemB, at itsupper end, and a follower, G, which is operated by rotating the nut D, resting on a stationary strainbeam, E, thus causing the screw G, supporting the follower O, to rise in the cotton-chamher in the usual manner, the screw being prevented from turning by a ratchet-wheel, a, and pawlcgconnecting it with the follower,

as in my Patent No. 213,384. After thefill of the cotton-box has .beenthus run up into the compression-chamber the ratchet-wheel a is released by disengaging the pawl 0, when the screw G, having a steel washer, e, interin the follower to reduce the friction, will immediately run down by its own gravity, the compressed cotton being retainedin the veningbetween its upper endand the socket upper part,- A, of the box by any suitable,

MA lateral chamber, L, ektending from the V broad side of the lower half of the cottonbox A, is provided with a follower, N, and screw B. After the first filling of cottonhas been run up into the compression-chamber A and the follower run down, the lateral follower N, which forms one side of the balingbox, is run back, when said box, with its lateral extension, may be filled with cotton from the ordinary condenser, and the followerN run in to close the side of the baling-box, after which the main follower C may be run up, as before, to compress the cotton into the chamber A. This may be repeated until the cotton in the compression-chamber is tightly packed. "By this means all trainping of the cotton is entirely dispensed with.

:10 represents a roller loosely hinged to the platen B, so that it may be turned upward, as shown at as, Fig. 6, forthe insertion of the bagging, and afterward lowered betweensaid platen and the upper edge of the doors of the chamber A, to prevent them from rising by the friction of the cotton being pressed upward.v

00 represents a rectangular strip which may be substituted for the roller x,- but I think the latter preferable.

The main follower G is provided with four angle-posts or guides, d, and the cotton-box is cut off on both sides on the line h h, Fig. 1,

leaving space between the strain-bea1ns E and.

bottom of the box for the follower to descend clear of thelatter, to admit of the insertion of the bagging previous to running the follower up for the last time; and in order to prevent any possibility of the follower getting out of line with the cotton-box I put a bar, It, on each side, about midway between the bottom of the box and the strain-beam E.

The socket M in the under side of the follower is made conical, slightly larger at its outer than at its inner end, where it is exactly the same diameter as the end of the cylindrical nose n of the screw. This is to avoid the liability of springing or bending the screw by the follower being depressed more at one end than at the other, owing to uneven packing of the cotton while baling.

The pressure-plate M, (represented in Figs. 7 and 8,) on which the collar or flange of the screw-nut D rotates, is formed with a central hole, M, of sufficient size for the lower por- 'nection with the draft-beams.

tion of the nut to pass freely through for 0011- Around this hole M is an upwardly-projecting collar, (1, fitting in an annular groove around the shank portion of the nut, and in the under side of its flange portion, outside of this collar a, is a plain surface, 0, on which the flange portion of the nut D rotates, and at the outer periphery of this flange is another rim or collar, a, for the most part concentric with the nut D, but having radial extensions at two opposite sides, encircling the oil-wells c, which sink slightly below the level of the bearing-surface c and across the latter, so that when said wells are filled with oil they afford a continual supply to the bearing of the nut, the collars a and a preventing its escape and waste.

Another feature of my invention consists in a novel method of securing the main doors of the compression-chamber, in which L L rep resent washers, (shown more clearly in Figs. 4 and 5,) which are secured to the inside of each end of the strain-beams N by eyebolts m. These washers are provided with a projection or tenon extending from its face and edge. The portion 1) is let into the strain-beam to the point of the hook t, instantly liberates the doors, while there is no liability of the latter being freed, whether under pressure or otherwise, unintentionally.

The old method of fastening is shown at X, Figs. 1 and 3, as applied to the supplemental doors H. This plan is very objectionable, as

the strain in packing is liable to spring the box and throw the hooked bars off, which not only injures the press, but is dangerous to the operators.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The hinged mechanism a: w, substantially as described, in combination with the platen B and doors of the compression-chamber A, substantially as and for the purpose set forth.

2. The conical .socket N on the follower O, in combination with the cylindrical nose at of the screw G, for the purpose specified.

3. The pressure-plate M, having a central hole, M, with collar a around said hole, in combination with the nut D, having an annular groove in the bearing portion of said nut, around its shank, to prevent the escape of oil, substantially as shown and described.

4. The washer-plates L, constructed with projections 19 and r and abutment-edge w, and secured to the ends of the strain-beams N by eyebolts m, in combination-with the slip-link fastening T, all constructed and operating substantially as described. 7
